Power cord upgrade


I want to upgrade power cords for my streamer, Aurender A15 which currently has a Shunyata v14 digital.

And Puritan 156 which has the classic cord it comes with.

I believe in system synergy, so I am leaning towards Transparent, and/or Audioquest.

I have ARC ref5se with the Transparent Reference, and ref75se with the AQ Hurricane.

Guess my thought is the streamer and 156 PC are maybe a bottleneck. Won't know without trying, right? I am satisfied with the over all sound now, so looking for more of it. Make any sense??

There’s no 40 year debate here. This is thousands year old debate of random gimps entering conversations they should be no part of to share opinions they can’t substantiate.
 

The OP had asked for a power cord recommendation for a specific component within context of a specific system. And the opinions of those who never even stood within a distance to be able to read the make and model of these components and cables are pouring in. Hoarders of vintage low-fi stereos that retailed for $50 brand new 50 years ago that have captive power cords telling you there’s no difference in cables. Others with DIY garbage kits and low resolution speakers that have been listening to their systems at 115db levels for 30 years share their thoughts on how it’s impossible to hear differences between cables.
 

Gotta love the forums on the internet where you can obtain a legit qualified opinions on everything from cables to marriage counseling from people who have no experience in either. 
Keep it coming! Entertainment is awesome here!

That in-itself is a whole lot of opinion with a little sour to boot. You know the old Christmas Carol ‘Do you hear what I hear’ lol 

Thanks @audphile1 , you just saved me the time. If you can't hear the difference, you need a better system, or better ears. The only point I can agree on with the naysayers is that science cannot yet explain it.

So there it is without any of the Animosity, Science cannot yet explain it ! Get better ears because one doesn’t hear what an another does? Get a better system because they’ve been able to ‘substantiate’ sight unseen the quality of others. Wow ‘Heap’ 💩 of faith to be sure. 

Science cannot explain how old the universe is. That number changes every 20-25 years. Oscilloscopes can’t tell me what my system sounds like. Nobody knows 💩. So that’s that for science.
